DETAILED DESCRIPTION

While the disclosed subject matter is amenable to various modificationsand alternative forms, specific embodiments have been shown by way ofexample in the drawings and are described in detail below. Theintention, however, is not to limit the disclosure to the particularembodiments described. On the contrary, the disclosure is intended tocover all modifications, equivalents, and alternatives falling withinthe scope of the disclosure as defined by the appended claims.

As the terms are used herein with respect to ranges of measurements(such as those disclosed immediately above), “about” and “approximately”may be used, interchangeably, to refer to a measurement that includesthe stated measurement and that also includes any measurements that arereasonably close to the stated measurement, but that may differ by areasonably small amount such as will be understood, and readilyascertained, by individuals having ordinary skill in the relevant artsto be attributable to measurement error, differences in measurementand/or manufacturing equipment calibration, human error in readingand/or setting measurements, adjustments made to optimize performanceand/or structural parameters in view of differences in measurementsassociated with other components, particular implementation scenarios,imprecise adjustment and/or manipulation of objects by a person ormachine, and/or the like.

As stated above, law enforcement officers and non-law enforcement peoplemay use body cameras and/or other types of cameras to record events whenusing guns, such as encounters between a gun's user and one or morethird parties. In many instances, though, a law enforcement officerand/or non-law enforcement person may unintentionally block the view ofthe camera with his/her arms when the gun is drawn. Additionally oralternatively, the person may not activate the body camera at theappropriate time. In these instances, body cameras may not providesupport that the law enforcement officer's use of the gun was justifiedor unjustified and/or may not record the event that the non-lawenforcement person wishes to record. Stationary cameras and/ornon-stationary cameras, on the other hand, may not provide the bestperspective of an event, especially if a user is moving. Accordingly,body cameras suffer from many drawbacks including failure to activate atappropriate times, obstructed views depending on the positioning of thebody camera and/or providing a less than desirable perspective of anevent.

Embodiments of the present disclosure may overcome these limitations. Inparticular, the embodiments herein disclose gun-mounted recordingdevices. Additionally, upon determination of an event, a recordingdevice mounted to a gun may transition from a lower-power state to ahigher-power state automatically. Embodiments of the present disclosuremay also have the advantage of eliminating user discretion for when/ifto record an event. Furthermore, the embodiments provided herein may beused by law enforcement and non-law enforcement when no other recordingdevice is currently being used.

As used herein, “events” may be occurrences when a gun is deployed froma previously un-deployed position. For example, an event may be when auser (e.g., law enforcement and/or non-law enforcement) deploys his/hergun from his/her holster during an encounter between the user and athird party. As another example, an event may be when a user of a gundeploys a gun from a safe and/or picks up the gun from a flat surface, anightstand drawer, an automobile glove box, from clothing, gun case,duty belt and/or the like. However, these are only examples and notmeant to be limiting. In addition, while the term “gun” is being usedthroughout this description, the recording device may be coupled toother devices that may not be considered guns, such as bows, crossbowsand/or other devices not considered guns that shoot projectiles.

FIGS. 1-3 depict different views of a handgun 102 with a recordingdevice 104 attached thereto, in accordance with embodiments of thepresent disclosure. The handgun 102 includes, among other elements andfeatures, a barrel 106 and a trigger guard 108. In embodiments, thebarrel 106 includes a rail system 110 that is configured to accommodatea variety of different accessories and attachments, including theability to attach the recording device 104 to the rail system 110.Additionally or alternatively, the handgun 102 may include otherattachment points to which the recording device 104 can be attached, forexample, a trigger guard mount, a grip mount and/or other attachmentpoints on the handgun 102. While a handgun is depicted in FIG. 1, therecording devices 104 described herein may be used with a variety ofdifferent gun styles and sizes, including handguns, rifles, shotgunsand/or the like, as well as other devices not considered guns, but shootprojectiles. As such, the handgun 102 depicted in FIG. 1 is meant forillustrative purposes and not meant to be limiting.

As shown, the recording device 104 may be secured to the rail system 110ahead of the trigger guard 108. In some embodiments, the recordingdevice 104 is configured such that the recording device 104 does notextend beyond a muzzle end 112 of the barrel 106. In other embodiments,the recording device 104 may extend beyond the muzzle end 112. It willbe appreciated that the rail system 110 may vary somewhat, depending onthe type of gun used. As set forth above, while the recording device 104is shown as attached to the rail system 110, the recording device 104may be attached to other attachment points on the handgun 102 including,for example, a trigger guard mount, a grip mount and/or like.

In embodiments, the recording device 104 may be configured to transitionfrom a lower-power state to a higher-power state in response to adetermination that the handgun 102 is being deployed. Embodiments fordetermining the handgun 102 is being deployed are discussed in moredetail below. Once in a higher-power state, the recording device 104 mayrecord one or more of the following: a visual aspect, an audio aspect, amotion aspect of the gun, a temperature aspect, a pressure aspect, date,time and/or location of the recording device 104. In embodiments wherethe recording device 104 records a video aspect and/or an audio aspect,the recording device 104 may include a camera and/or a microphonedisposed on an end 114 of the recording device 104. The camera and/ormicrophone disposed on the end 114 of the recording device 104 may beforward facing along a longitudinal axis 116 of the barrel 106 to senseand record video and/or audio, respectively, that is in front of thehandgun 102. In embodiments, the camera and/or microphone on the end 114of the recording device 104 may be configured to sense and record videoand/or audio that is 1 foot, 5 feet, 10 feet, 25 feet, 50 feet, 100 feetand/or the like in front of the handgun 102. In embodiments, the cameraon the end 114 of the recording device 104 may have a fixed focal lengthor include an autofocus to focus. Additionally or alternatively, thecamera may include more than one camera. For example, multiple camerasmay be used to record multiple views (e.g., a view of the user of thehandgun 102, a view of what the user is pointing the handgun 102, sideviews, and/or the like). Additionally or alternatively, the multiplecameras may be configured to: record a non-zoomed-in view and azoomed-in view and/or have different focal lengths, at different framesper second, at different resolutions, and/or the like. Further detailsof the recording device 104, as well as details of how the recordingdevice 104 attaches to the handgun 102, will be discussed with respectto subsequent Figures.

FIGS. 4-8 depict different views of the handgun 102 and the recordingdevice 104 inserted into the holster 118, in accordance with embodimentsof the present disclosure. The recording device 104 is obscured by theholster 118 and cannot be seen. In embodiments, the holster 118 mayinclude a securement portion 120 that is configured to be secured to auser's belt. Additionally or alternatively, the holster 118 may beconfigured to interact with the recording device 104 to releasablysecure the handgun 102 within the holster 118 without engaging thetrigger guard 108. In other embodiments, the holster 118 may beconfigured to interact with the trigger guard 108 to releasably securethe handgun 102 within the holster 118 without engaging the recordingdevice 104. In even other embodiments, the holster 118 may be configuredto interact with both the recording device 104 and the trigger guard 108to releasably secure the handgun 102 within the holster 118.

In embodiments, upon removal of the handgun 102 from the holster 118,the recording device 104 may transition from a lower-power state to ahigher-power state. For example, the holster 118 may include one or moremagnets 122 that produce a magnetic field that can be detected by asensor of the recording device 104. In embodiments, the recording device104 may transition from a lower-power state to a higher-power state ifthe sensor of the recording device 104 does not sense a magnetic fieldthat is above a threshold value. That is, if the handgun 102 is deployedfrom the holster 118, the magnetic field emanating from the one or moremagnets 102 may no longer be able to be sensed by a sensor of therecording device 104 and, in response, the recording device maytransition from a lower-power state to a higher-power state. In someembodiments, the one or more magnets 122 may be embedded within a panelof the holster 118, on an interior portion of the holster 118 and/or onan exterior portion of the holster 118. Additionally or alternatively,while one magnet 122 is depicted, more magnets may be used and/or themagnet 122 may be located at other positions of the holster 118.Additionally or alternatively to the holster 118 including one or moremagnets 122, the one or more magnets 122 may be disposed on a flatsurface such as the floor of a safe, a nightstand drawer, an automobileglove box and/or the like. As such, the recording device 104 maytransition from a lower-power state to a higher-power state when, forexample, a user of a handgun 102 deploys the handgun 102 from a safeand/or picks up the handgun 102 from a flat surface, such as anightstand drawer, an automobile glove box and/or the like.

Additionally or alternatively to transitioning from a lower-power stateto a higher-power state upon removal of the handgun 102 from the holster118, the recording device 104 may transition from a higher-power stateto a lower-power state when the handgun 102 is placed in the holster118. For example, the recording device 104 may transition from ahigher-power state to a lower-power state in response to sensing amagnetic field, emanating from one or more magnets 122, that is above athreshold value.

Additionally or alternatively to transitioning from a lower power stateto higher-power state and from higher-power state to a lower-power statein response to sensing a magnetic field, the recording device 104 maytransition from a lower-power state to a higher-power state when anoutput of one or more of the following sensors and/or switches indicatesthe handgun 102 is being deployed: a pressure switch, a proximitysensor, a reed switch, a motion sensor, a gyroscope, an audio sensor, abiometric sensor, and/or an accelerometer. Additionally oralternatively, the recording device 104 may transition from ahigher-power state to a lower-power state when an output, of one or moreof the following sensors and/or switches, indicates the handgun 102 isin an un-deployed state: a pressure switch, a proximity sensor, a reedswitch, a motion sensor, a gyroscope, an audio sensor, a biometricsensor, and/or an accelerometer. In embodiments, the sensor and/orswitch may be located on the recording device 104 and/or on any otherposition on the handgun 102 that facilitates determining the handgun 102is in a deployed state and/or an un-deployed state.

In embodiments, the audio sensor may respond only to a specific voice,sound, and/or word. That is, a user may train the audio sensor torespond to a specific voice, sound, and/or word. Additionally oralternatively, the biometric sensor may only respond to specificbiometric indicators, for example, fingerprint, palm print, facialfeatures, eye, iris, retina, voice, venous pattern, and/or the like.Similar to the audio sensor, a user may train the biometric sensor torespond to a specific biometric indicator.

FIG. 9 depicts a portion of the handgun 102 without the recording device104 coupled thereto, in which the rail system 110 includes a leftprofile 124 (in the illustrated orientation) and a corresponding rightprofile 126. In embodiments, the rail system 110 also includes ahorizontal cross slot 128. In embodiments, the rail system 110 may beused in combination with a rail set 130A, 130B attached to the recordingdevice depicted in FIGS. 10-17.

FIGS. 10-17 depict different views of the recording device 104, inaccordance with embodiments of the present disclosure. In the embodimentshown, the recording device 104 includes a rail set 130A, 130B. In someembodiments, the rail set 130A, 130B includes a left portion 130A and aright portion 130B that are configured to engage the left profile 124and the right profile 126 of the rail system 110. In some embodiments,as illustrated, the rail set 130A, 130B may include mounting apertures132 that permit the cross pins (not shown) to extend through theapertures 132 and secure the rail set 130A, 130B to the rail system 110.In some embodiments, the rail system's 110 horizontal cross slot 128 issized and positioned to accommodate cross pins that extend through theapertures 132 and thereby prevent or at least substantially preventlateral movement of the recording device 104 relative to the handgun102. In some embodiments, the rail set 130A, 130B may include severaldifferent mounting apertures to accommodate handguns 102 havingdifferent positions for the horizontal cross slot 128. As such, it willbe appreciated that the recording device 104 may be attached to avariety of different guns or handguns 102 without requiring alterationof the recording device 104. Rather, the rail set 130A, 130B may beconfigured to have mounting surfaces that are configured to interactwith the particular rail system 110 of a particular gun 102. Furtherdetails of embodiments of mounting devices for a gun are disclosed in,for example, U.S. patent application Ser. No. 14/583,342, entitled “GunHolster and Electronic Assembly,” which is hereby incorporated byreference in its entirety. Additionally or alternatively, the recordingdevice 104 may be mounted to the handgun 102 via other methods, suchusing a trigger guard mount and/or a grip mount. This recording device104 could be integrated into the gun.

As stated above, the recording device 104 may include a recording module134 configured to record one or more of the following: a visual aspect,an audio aspect, a motion aspect of the gun, a temperature aspect, apressure aspect, date, time and/or location of the recording device 104.In embodiments, the recording module 134 may begin or cease recording inresponse to one or more signals, as described in more detail below.

In embodiments where the recording module 134 is configured to record avisual aspect, the recording module 134 may be a video camera with alens disposed on an end 114 of the recording device 104. In embodiments,the recording module 134 may be configured to focus at differentdistances, record at different frames per second, record at differentresolutions, and/or the like. To capture video in low light, therecording device 104 may include a light-emitting diode 136 (LED) (orother type of lighting device) that is capable of illuminating areas infront of the recording device 104. Additionally or alternatively, thevideo camera may be configured to capture video in low light with orwithout the use of the LED 136. Additionally or alternatively, therecording device 104 may be configured to include a time stamp on anyrecordings. The time stamp may indicate a local time that the recordingwas recorded.

Additionally or alternatively, the recording device 104 may include alaser that facilitates aiming of a gun (or other device configured toshoot a projectile) to which the recording device 104 is attached. Inembodiments, the recording device 104 may include a green, red, blueand/or other color laser sight(s) for determining where the handgun 102and/or the recording device 104 are pointed. An example of a green laserlight that may be incorporated into the recording device 104 isdisclosed in U.S. patent application Ser. No. 13/720,083, entitled “AutoOn Green Laser Sight,” which is hereby incorporated by reference in itsentirety.

Additionally or alternatively, the recording device 104 may include amicrophone for recording an audio aspect, a temperature sensor forsensing a temperature of the environment of the recording device 104, apressure sensor for sensing a pressure of the environment of therecording device 104, one or more motion sensors (e.g., gyroscopes,accelerometers and/or the like) for sensing motion of the recordingdevice 104, one or more sensors for measuring times and/or dates, one ormore sensors for recording biometric indicators, and/or one or morelocation sensors (e.g., a GPS receiver) for measuring the location ofthe recording device 104. In embodiments, the pressure sensor forsensing pressure of the environment of the recording device 104 may be adifferent than the pressure sensor used for determining whether or notthe handgun 102 is deployed or un-deployed.

To power the recording device 104, the recording device 104 may includean onboard power source 138 (e.g., a battery). In embodiments, the powersource 138 may be replaceable, rechargeable and/or removable.Additionally or alternatively, the power source 138 may be a customizedpower source 138 and may include spring contacts that allow the powersource 138 to be removable. In embodiments where the power source 138 isrechargeable, the power source 138 may be recharged via a wire (e.g.,via a power cord coupled to the recording device 104 and/or the powersource 138) and/or may be recharged wirelessly, (e.g., inductively).Additionally or alternatively, the power source 138 may be removable andcoupled with a base station to recharge the power source 138.

In embodiments, the recording device 104 may also include an indicator140 disposed on the left side and/or right side of the recording device104. The indicator 140 may indicate the remaining amount of power of thepower source 138 and/or how much memory is left for recording video,sound, etc. Additionally or alternatively, the indicator 140 mayindicate whether the recording device 104 is recording. As examples, theindicator 140 may be a light that is capable of displaying differentcolors (e.g., green, yellow and red) and/or different light sequences,which indicate whether the recording device 104 is recording and/or theremaining amount of power of the power source 138. For example, lightbeing emitted from the indicator may indicate that the recording device104 is recording. As another example, a green light displayed by theindicator 140 may indicate that the power source 138 has enough powerleft to power the recording device 104 for a first threshold amount oftime (e.g., 1 hour, 2 hours, 6 hours, 12 hours and/or the like). Ayellow light displayed by the indicator 140 may indicate that the powersource 138 has enough power to power the recording device 104 a secondthreshold amount of time (e.g., 10 minutes, 20 minutes, 30 minutes, 1hour, 2 hours and/or the like), but not enough power to power therecording device 104 for the first threshold amount of time (e.g., 1hour, 2 hours, 6 hours, 12 hours and/or the like). A red light displayedby the indicator 140 may indicate that the power source 138 does nothave enough power to power the recording device 104 for the secondthreshold amount of time (e.g., 10 minutes, 20 minutes, 30 minutes, 1hour, 2 hours and/or the like). Additionally or alternatively, somefunctions of the indicator 140 may be incorporated into the handgun 102(e.g., indicator lights on the back of the gun) to facilitate viewing ofthe indications.

In embodiments, one or more thresholds (e.g., the first threshold and/orthe second threshold) may correspond to average shift times for a policeofficer and/or, in embodiments, assume an average amount of use over thecorresponding time periods. For example, a green light may indicate thatthe power source 138 has enough power to power the recording device 104for the entirety of an average police officer shift if the recordingdevice 104 is used an average amount during the entirety of the shift.The average amount of use may correspond to the recording device 104spending an average amount of time spent in a lower-power state and/oran average amount of time in a higher-power state. These states aredescribed in more detail below in relation to FIG. 18. As anotherexample, the yellow light may indicate that the power source 138 hasenough power to power the recording device 104 for half the averageshift duration if the recording device 104 is used an average amountduring the entirety of the shift. And, a red light may indicate that thepower source 138 needs to be either replaced and/or recharged before thepolice officer begins his/her shift.

In embodiments, the recording device 104 may include two modes: one modewhere a user cannot modify one or more settings of the recording device104 (e.g., when the recording device 104 records) and another mode wherea user can modify one or more of the settings of the recording device104. In the embodiments where a user cannot modify one or more settingsof the recording device 104, one or more settings of the recordingdevice 104 may only be modified by an administrator. Additionally oralternatively, while a user may not be able to modify one or moresettings, the user may be able to view and/or listen to the recordings,but may not be able to modify the recordings.

In embodiments, the recording device 104 may include one or more userinterface buttons 142 disposed on the left side and/or right side of therecording device 104. A user interface button 142 may provide a userand/or administrator, depending on the mode of the recording device 104,with the ability to program and/or modify the functionality of therecording device 104. For example, the user interface button 142 mayprovide an administrator the ability to determine when and how therecording device 104 records, how long the recording device 104 recordsand/or the like. Additionally or alternatively, the user interfacebutton 142 may control the operation of the LED 136 and/or otherfunctions included in the recording device (e.g., a microphone, atemperature sensor, a pressure sensor, audio sensor, biometric sensor,and/or a laser gun sight). In some embodiments, some functions of theuser interface button 142 may be controllable by a non-administratorwhile others may only be controllable by an administrator. For example,recording aspects of the recording device 104 (e.g., when and how longthe recording device 104 records) may only be controllable by anadministrator while a non-administrator may be able to control a laserand/or light of the recording device 104. In some embodiments, theinterface button 142 may be replaced by a touchscreen or other userinterface. In some embodiments, before being able to modify one or moresettings of the recording device 104, a specific code and/or otherauthorizing indicia (e.g., a biometric identifier) may need to beentered into the user interface button 142 before the user has theability to modify the functionality of the recording device 104. Thismay prevent some users from controlling the settings of the recordingdevice 104, while still allowing other users (e.g., administrators) tohave access to the settings of the recording device 104. Additionally oralternatively, some functions of the interface button 142 may bereplaced and/or replicated by an application on a smartphone.

The recording device 104 may also include a processing device 144, asdepicted in FIGS. 15 and 17. The processing device 144 may control thefunctionality of the recording device 104, as described below inrelation to FIGS. 18 and 19. Additionally, in embodiments, the recordingdevice 104 may include memory (not shown) to store any data recorded bythe recording device 104.

Additionally or alternatively, a sensor 146, as depicted in FIG. 17, maybe coupled to the processing device 144. The sensor 146 may be, forexample, a Hall-effect sensor that detects a magnetic field strengthfrom, for example, the magnet 122, a motion sensor (e.g., anaccelerometer and/or gyroscope), a pressure sensor, a proximity sensor,an audio sensor, a reed switch, and/or the like. In embodiments, thesensor 146 may be configured to sense when the gun 102 is deployedand/or not deployed. For example, the sensor 146 may be configured tosense when the gun 102 is positioned, for example, within the holster118 and/or when the gun 102 is not in use. In these embodiments, theprocessing device 144 may transition from a higher-power state where therecording device 104 is recording to a lower-power state where therecording device 104 is not recording, in response to receiving a signalfrom the sensor 146 indicating the gun 102 is positioned within theholster 118 and/or not in use. Conversely, the processing device 144 maytransition from a lower-power state to a higher-power state where therecording device 104 is recording in response to the sensor 146 sensingthe gun is not positioned within the holster 118 and/or when the gun 102is deployed. These embodiments are discussed in more detail below inrelation to FIG. 18.

In embodiments, the recording device 104 may include a data port 148, asdepicted in FIG. 13, for transferring data to and from the recordingdevice 104. In embodiments, a cover 150 may cover the data port 148 whenthe data port 148 is not being used to prevent the data port 148 frombeing damaged by, for example, debris. Additionally or alternatively,the recording device 104 may include a receiver and/or transmitter (notshown) for wireless receiving and/or transmitting data to and from therecording device 104. In embodiments, the data port 148, receiver and/ortransmitter may be configured to transmit data at certain timeincrements, upon demand, after an event is recorded and/or after thememory of the recording device 104 has less than a threshold amount ofopen space available for future recordings. In embodiments, the dataport 148 and/or data management system of the recording device 104 maybe compatible with existing law enforcement and/or other data managementsystems.

FIG. 18 is a block diagram of an embodiment of a system 200 including agun 202 and a recording device 204 mounted thereto, in accordance withembodiments of the present disclosure. In embodiments, the gun 202 maybe a handgun, a rifle, a shotgun, a device for shooting a projectile,and/or the like. The recording device 204 may have some or all of thesame functionality as the recording device 104 depicted in FIGS. 1-17;conversely, the recording device 104 depicted in FIGS. 1-17 may havesome or all of the same functionality as the recording device 204depicted in FIG. 18. For example, the recording device 204 may bemounted to the gun 104 using a rail mounting system (e.g., the railsystem 130 depicted in FIG. 9.) Additionally or alternatively, therecording device 204 may be mounted to the gun using other methods knownin the art, such as a trigger guard mount and/or a grip mount.

In embodiments, the recording device 202 may include one or more of thefollowing components: one or more sensors 206, a processing device 208,a recording module 210, memory 212, a data port 214, a transceiver 216,a user interface 218 and/or a power source 220. While the abovecomponents 206-220 are depicted as being included in the recordingdevice 204, one or more of the components 206-220 may be locatedexternal to the recording device 204.

In embodiments, the sensor(s) 206 may be configured to sense a signalthat corresponds to the gun 202 being deployed. As indicated above, tobe deployed, the gun 202 does not have to be fired. Instead, the gun 202may be deployed if it is withdrawn from a holster and/or safe, picked upfrom a surface (e.g., a nightstand drawer, automobile glove box and/orthe like), activated via an audio command, activated via a biometricindicator, moved in such a way that would indicate that a user is usingthe gun 202, such as pointing the gun 202 at a target, in the vicinityof a target, moving the gun in a defensive manner and/or for an expectedengagement, and/or in a direction in which the user believes there to bea target.

As an example, to determine that the gun 202 has been deployed, thesensor(s) 206 may sense whether the sensor(s) 206 is in the presence ofa magnetic field of a sufficient strength. That is, a magnet (e.g., themagnet 122 depicted in FIGS. 4, 6, 8) may be disposed on or in aholster, safe and/or surface. When the sensor(s) 206 is within a certaindistance of the magnet, the sensor(s) 206 will sense a magnetic field ofa designated strength. Alternatively, when the sensor(s) 206 is moved asufficient distance away from the magnet, the sensor(s) 206 will nolonger sense a magnetic field of a designated strength. As such, thesensor(s) 206 sensing that the strength of a magnetic field is below adesignated strength may indicate that the gun 202 is deployed from, forexample, a holster, a safe and/or picked up from a surface. As anexample of a sensor 206 that may sense the presence or absence of amagnetic field, the sensor(s) 206 may be a Hall-effect sensor.

As another example, the sensor(s) may sense a specific movement of thegun 202 to sense whether the gun 202 is in use. For example, thesensor(s) 206 may be accelerometers and/or gyroscopes. In this example,the sensor(s) 206 may sense if there is motion of the gun 202 in adirection that is greater than a threshold length, motion of the gun 202that persists for more than a threshold amount of time, a change inangular direction of the barrel of the gun 202 that is greater than athreshold angle and/or a change in angular direction of the gun 202changes at a rate faster than a threshold rate. In embodiments, thethreshold length, threshold amount of time, threshold angle and/or thethreshold rate may be configurable and/or user dependent. Other examplesensors that may be used to determine whether the gun 202 has beendeployed include, but are not limited to, a pressure sensor, a proximitysensor, a reed switch, and/or the like.

The signals sensed by the sensor(s) 206 may be transmitted to theprocessing device 208. In response to receiving a signal indicating thatthe gun 202 is in use, the processing device 208 may transition itselfand/or the recording module 210 from a lower-power state to ahigher-power state. In embodiments, the recording module 210 may beconfigured to record one or more of the following: a video camera forrecording a visual aspect, a microphone for recording an audio aspect, atemperature sensor for sensing a temperature of the environment of therecording device 204, a pressure sensor for sensing a pressure of theenvironment of the recording device 204, one or more motion sensors(e.g., gyroscopes, accelerometers and/or the like) for measuring motionof the recording device 204, date, time and/or location of the recordingdevice 204. Similar to above, the pressure sensor for sensing pressureof the environment of the recording device 204 may be a different thanthe pressure sensor used for determining whether or not the handgun 202is deployed or un-deployed. Additionally or alternatively, the recordingdevice 204 may be configured to include a time stamp on any recordings.The time stamp may indicate a local time that the recording wasrecorded.

In embodiments, the higher-power state is a state where the recordingmodule 210 can record one or more aspects of the environment of the gun202. In embodiments, the lower-power state may be when the processingdevice 208 is in a low-power sleep mode and the recording module 210 isin an off state. When the lower-power state is a low-power sleep modefor the processing device 208 and/or an off state for the recordingmodule 210, the power consumed by the recording device 204 is at itslowest. However, the time required for the recording module 210 totransition from a lower-power state to a higher-power state is thelongest. In embodiments, the longevity of the power source 220 may beadvantageous. At other times, the time delay to transition from alower-power state to a higher-power state may be a disadvantage and ashorter delay may be desirable.

As such, in embodiments, the lower-power state may be a low-power sleepmode for the processing device 208 and the recording module 210. Inthese embodiments, the recording module 210 may be capable oftransitioning from the lower-power state to a higher-power state inapproximately 2 seconds or less. Additionally or alternatively, the timedelay to transition from a lower-power state to a higher-power state maybe configured to be less than the average time it takes for a lawenforcement officer to draw his/her gun out of his/her holster. In theseembodiments, the power source 220 will not last as long as when thelower-power state is an off state; however, the reduced time delay totransition from a lower-power state to a higher-power state for therecording module 210 may be advantageous for a user of the recordingdevice 204. For example, if the user would like to begin recording anencounter less than a couple of seconds after the sensor(s) 206 sensesthat the gun 202 is in use, this lower-power state may be desirable.

Alternatively, in embodiments, the lower-power state may be a mode inwhich the processing device 208 is operating normally but the recordingmodule 210 is still in a lower-power sleep mode. In these embodiments,the recording module 210 may be capable of transitioning from thelower-power state to a higher-power state in approximately 0.5 secondsor less. In these embodiments, the power source 220 will not last aslong as when the lower-power state is in one of the other lower-powersleep modes; however, the reduced time delay to transition from alower-power state to a higher-power state by the recording module 210may be desirable for a user when the user would like the recordingmodule 210 to begin recording almost as soon as the sensor(s) 206 sensesthe gun 202 is in use.

In embodiments, the recording device 204 may allow a user to switchbetween the different lower-power states described above via the dataport 214, the transceiver 216 and/or the user interface 218.Alternatively, in embodiments, only an administrator of the recordingdevice 204 may be able to switch between the different lower-powerstates described above via the user interface 218 and/or via the dataport 214, the transceiver 216 and/or the user interface 218. This mayprevent a user of the recording device 204 from accidentally orintentionally tampering with the recording device 204.

The processing device 208 may be any arrangement of electronic circuits,electronic components, processors, program components and/or the likeconfigured to store and/or execute programming instructions, to directthe operation of the other functional components of the recording device204 and may be implemented, for example, in the form of any combinationof hardware, software, and/or firmware.

In embodiments, the recordings may be incremented at specified timeincrements (e.g., 5 minutes, 10 minutes, 20 minutes, 30 minutes and/orthe like). As such, when reviewing any of the recordings, a user may beable to quickly fast forward through specified time increments by movingfrom one indexed recording to the next. Additionally or alternatively,the recordings may be: indexed (e.g., 1, 2, 3, etc.; 01, 02, 03, etc.;001, 002, 003, etc.; 0001, 0002, 0003, etc.; A, B, C, etc. and/or thelike) and/or include time stamps.

In embodiments, the recordings of the recording module 210 may be savedin memory 212. The saved recordings may be password protected,encrypted, access limited (e.g., only an authorized user such as anadministrator may have access to the saved recordings on memory 212),and/or the like. In embodiments, the recordings may be segmented intomultiple files that include 1 minute, 2 minute, 3 minute, and/or thelike segments. In embodiments, if the memory 212 is full the recordingsmay loop and save over the earliest saved recordings in memory 212. Inembodiments, segmenting the recordings into multiple files mayfacilitate reducing the amount of recordings that are recorded over incomparison to embodiments where the recordings are saved as one file. Inembodiments, saving over the earliest saved recordings in memory 212 maybe disabled, so that once memory 212 is full, the recording stops savingto memory 212 and, in embodiments, only transmits the data via acommunication link 228 to an external communication device 222. Inembodiments, the memory 212 may be incorporated into the recordingdevice 204 or external to the recording device 204. In embodiments, thesystem 200 may include internal and/or external memory devices 212. Inembodiments, the memory 212 includes computer-readable media in the formof volatile and/or nonvolatile memory and may be removable,nonremovable, or a combination thereof. Media examples include RandomAccess Memory (RAM); Read Only Memory (ROM); Electronically ErasableProgrammable Read Only Memory (EEPROM); flash memory; optical orholographic media; magnetic cassettes, magnetic tape, magnetic diskstorage or other magnetic storage devices; data transmissions; and/orany other medium that can be used to store information and can beaccessed by a computing device such as, for example, quantum statememory, and/or the like, including memory that may be compatible withexisting law enforcement and/or other data management system.

In embodiments, the recordings may be transmitted to an externalcommunication device 222 via a network 224 where the recordings can besaved on a server 226. In embodiments, recordings may also betransferred from the recording device 204 to the server 226 via awireless or wired connection (e.g., via the data port 214). Inembodiments, the data management of the recording device 204 may becompatible with existing law enforcement data management systems andrequirements. Additionally or alternatively, the transmission may beencrypted via public-key encryption methods and/or other types ofencryption.

In embodiments, the recordings may be transmitted to the server 226 at aspecified time interval and/or upon demand. Additionally oralternatively, the recordings may be transmitted to the server 226 whena designated amount of space on the memory 212 has been used. Forexample, when 70%, 80%, 90%, and/or 100% of the memory 212 has beenused, the recordings may be transmitted to the server 226. Additionallyor alternatively, the recordings may be transmitted to the server 226upon certain conditions occurring (e.g., the gun 202 being fired and/ora law enforcement officer returning to the station at which he/sheworks).

In response to transmitting one or more recordings to the server 226,the server 226 may send a response to the recording device 204indicating the recordings that were received by the server 226 from therecording device 204. After transferring the recordings to a server 226,the processing device 208 may be configured to erase the recordingssaved on the memory 212. Alternatively, the recordings may only beerased from memory 212 by an authorized user (e.g., an administrator).

Additionally or alternatively, a recording that includes a portion wherethe gun 202 was fired may be stored on memory 212 with one or moreindicia indicating the gun 202 was fired. For example, the recording mayinclude an icon, a colored border and/or the like in a portion of thevideo. As another example, the recording may be indexed and/or saved onmemory 212 in a manner that identifies the recording as including aportion where the gun 202 was fired. In embodiments, recordings thatinclude a portion where the gun 202 was fired may immediately and/orautomatically be transmitted to a server 226 via the network 224. Inembodiments, the one or more indicia may be compatible with existing lawenforcement data management systems and requirements.

In embodiments, the network 204 may use a communication link 228. Inembodiments, the communication link 228 may be, or include, a wirelesscommunication link such as, for example, a short-range radio link, suchas Bluetooth, IEEE 802.11, a proprietary wireless protocol, and/or thelike. In embodiments, for example, the communication link 228 mayutilize Bluetooth Low Energy radio (Bluetooth 4.1), or a similarprotocol, and may utilize an operating frequency in the range of 2.40 to2.48 GHz. The term “communication link” may refer to an ability tocommunicate some type of information in at least one direction betweenat least two devices, and should not be understood to be limited to adirect, persistent, or otherwise limited communication channel. That is,according to embodiments, the communication link 228 may be a persistentcommunication link, an intermittent communication link, an ad-hoccommunication link, and/or the like. The communication link 228 mayrefer to direct communications between the recording device 204 and theexternal communication device 222, and/or indirect communications thattravel between the recording device 204 and the external communicationdevice 222 via at least one other device (e.g., a repeater, router, hub,and/or the like). The communication link 228 may facilitateuni-directional and/or bi-directional communication between therecording device 204 and the external communication device 222. Dataand/or control signals may be transmitted between the recording device204 and the external communication device 222 to coordinate thefunctions of the recording device 204 and/or the external communicationdevice 222. In embodiments, the communication link 228 may be compatiblewith existing law enforcement data management systems and requirements.

FIG. 18 is a flow diagram of an example method 300 for operating agun-mounted recording device with auto on, in accordance withembodiments of the present disclosure. In embodiments, the recordingdevice may have some or all of the same functionality as the recordingdevice 104 depicted in FIGS. 1-8 and 10-17 and/or the recording device204 depicted in FIG. 18. For example, the recording device may becoupled to a gun (e.g., the gun 102 depicted in FIGS. 1-17 and/or thegun 202 depicted in FIG. 18) and include a recording module, forexample, the recording module 104 depicted in FIGS. 1-8 and 10-17 and/orthe recording module 210 depicted in FIG. 18 for recording at least oneaspect of the gun's environment and/or the recording device'senvironment. In embodiments, the at least one aspect may be one or moreof the following: a visual aspect, an audio aspect, a motion aspect ofthe gun, a temperature aspect, a pressure aspect, date, time and/orlocation of the recording device. In embodiments, the recording deviceincludes an auto-on feature, as described in more detail below.

Method 300 includes receiving a signal associated with a gun beingdeployed (block 302). In embodiments, the signal may be received by aprocessing device (e.g., the processing device 144 depicted in FIGS. 15and 17 and/or the processing device 208 depicted in FIG. 18) that isincorporated into the recording device. As indicated above, to bedeployed, the gun does not have to be fired. Instead, the gun may bedeployed if it is withdrawn from a holster and/or safe, picked up from asurface (e.g., a nightstand drawer, automobile glove box and/or thelike) and/or moved the gun in such a way that would indicate that a useris using the gun, such as pointing the gun at a target, in the vicinityof a target and/or in a direction in which the user believes there to bea target.

The received signal may be provided by one or more sensors. Inembodiments, the one or more sensors may have some or all of the samefunctionality as the sensor 146 depicted in FIG. 15 and/or the sensor(s)206 depicted in FIG. 18. For example, the one or more sensors may sensethat the gun, to which the sensors are coupled, is in use by no longersensing a magnetic field above a specific threshold. That is, when thesensor is moved a sufficient distance away from a magnet that isdisposed in or on a holster, a safe and/or a surface, the sensor may nolonger sense a magnetic field above a specific threshold. A signalindicating that the sensor no longer senses a magnetic field above aspecific threshold may be transmitted by the sensor to a processingdevice. The processing device may then determine from the receivedsensed signal that the sensor is no longer in proximity to the magnetand, therefore, determine that the gun is in use. Further details ofembodiments of an auto-on feature are discussing in, for example, U.S.Pat. Appln. No. U.S. application Ser. No. 13/720,083, entitled “Auto-OnGreen Laser Sight,” which is hereby incorporated by reference in itsentirety.

Additionally or alternatively, one or more sensors may sense movement ofthe gun to which the sensors are coupled. For example, the one or moresensors may be accelerometers and/or gyroscopes. In this example, theone or more sensors may sense if there is motion of the gun in adirection that is greater than a threshold length, persists for morethan a threshold amount of time and/or changes the angular direction ofthe barrel of the gun. A signal indicating that the sensor senses one ormore of these types of movements may be transmitted by the one or moresensors to a processing device. The processing device may then determinefrom the received sensed signal that the gun is experiencing motion thatdoes not indicate normal jostling of a gun that is being carried, butinstead indicates that the gun is being pointed in a directionpurposefully. Other example sensors that may be used to determinewhether the gun 202 has been deployed include, but are not limited to, apressure sensor (e.g., a grip pressure sensor), a proximity sensor, areed switch, and/or the like.

After receiving a signal associated with a gun being in use, method 300may initiate a transition of the processing device and/or the recordingmodule of the recording device from a lower-power state to ahigher-power state (block 304). In embodiments, the higher-power stateand the lower-power state may be the same or similar to the higher-powerand lower-power states described above in relation to FIG. 18.

After the recording module of the recording device is in a higher-powerstate, the method 300 further includes recording at least one aspect ofthe gun's environment (block 306). In embodiments, the at least oneaspect of the gun's environment may be one or more of the following: avisual aspect, an audio aspect, a motion aspect of the gun, atemperature aspect, a pressure aspect, date, time and/or location of therecording device. In embodiments, the at least one recorded aspect maybe saved on memory (e.g., the memory 212 depicted in FIG. 18).

In embodiments, the method 300 may include transmitting, via a wiredand/or wireless transmission, the at least one recorded aspect to anexternal memory device (block 308). In embodiments, the external memorydevice may have some or all of the same functionality as the server 226depicted in FIG. 18. In embodiments, the transmission of the at leastone recorded aspect to an external device may be the same or similar tothe transmission of the recordings from the recording device 204 to theserver 226 as described above in relation to FIG. 18. For example, inembodiments, the processing device may receive a verification signalindicating that the transmitted signal from the processing device to theserver was received by the server (block 310). After the at least onerecorded aspect is transmitted to an external memory device, the atleast one recorded aspect may still be stored on memory of the recordingdevice.

Additionally or alternatively, the method 300 may include transitioningfrom the higher-power state to a lower-power state (block 312) inresponse to a sensor sensing the gun is not deployed, for example, hasbeen returned to a holster, safe and/or surface and/or the gun has notbeen moved in such a way that would indicate that a user is no longerusing the gun. After transitioning to a lower-power state, the recordingdevice may no longer be recording.
